This study examined microplastics in agricultural film-mulched cotton fields in Xinjiang, China, using soil samples from 60 sites with varying mulching histories. Microplastics were identified using oil separation and density separation, and stereomicroscopy and FTIR were used for identification. The average microplastic abundance was found to be 538, 1484, 5812, and 9708 pieces/kg, respectively. Microplastics with sizes of 1000–5000 and 200–500 μm were dominant in soils with less than 10 years and over 10 years of continuous mulching history. The study found a relationship between microplastic abundance and mulching years in different soil layers, with the topsoil layer having the best polynomial fitting curve. The results from the study revealed that residual agricultural mulching film was found to be the dominant source of microplastics in cotton fields, indicating the need for further research on microplastics prediction in agricultural film-mulched fields.
The Ocean Plastics Charter aims to bring together leading countries, sub-national governments, businesses, and civil society organisations to commit to a more resource-efficient and sustainable approach to keep plastics in the economy and out of the environment. With this charter, it aims to transition to a more sustainable and resource-efficient method of managing plastics. Through[…]
These regulations are intended to promote sustainable development, food security, and the sustainable management of fishing activities in Palau’s waters. They also intend to create economic returns, employment generation, and export earnings from the sustainable harvesting of tuna and tuna-like species by encouraging the development of domestic fishing industries and a local tuna market. These[…]
This subchapter E of Title 40 of the Code of Federal Regulations outlines the pesticide programs, including registration and classification procedures, policies, special review procedures, standards, labelling requirements, packaging requirements, data requirements, and good laboratory practice standards. It also covers state registration of pesticide products, rules of practice governing hearings under the federal Insecticide, Fungicide,[…]
The Plastics Roadmap aims to decrease littering and other environmental harm brought on by plastics, prevent needless use, enhance plastic recycling, and replace traditional polymers derived from fossil fuels combined with various substances and liquids. To guarantee more focus on sustainable product development, reuse, product recyclability, and the growing usage of recovered plastics, these objectives[…]
The regulations aim to enhance aquaculture pollution prevention and control, protect aquatic ecosystems, ensure product quality and safety, and promote sustainable development. They consist of 24 articles divided into four sections: general provisions, delimitation of prohibited areas, pollution prevention and control, and environmental monitoring and supervision of fishery waters.
